feat: MouseWheel

[melaurent]

I have added a method to get the MouseWheel values from the IO, it is returned as a Vec2 where X is horizontal scroll, and y vertical scroll.
I can create a merge request if people agree with the change

Hello there and thank you for the message!
Looking at the existing functions, there's AddMouseWheelDelta(horizontal, vertical float32) already. To have it symmetric regarding the axes, I'd go for MouseWheel() (float32, float32), so, returning two raw floating point values.
From a gut feeling these are rather two separate values rather than a combined vector to do math with.

And yes, feel free to do a pull request :)
